Specification of Letters Patent.

Patented Apr. Hi6, 1918.

Application filed March 27, 1917. Serial No. 157,803.

To all whom it may concern:

Be it known that I, HENRY ALBERT GUT- LER, a subject of the -King ofGreat Britain and Ireland, residing at Belfast, in the county of Antrim,Ireland, have invented Improvements in or Relating to Means for RemovingDeposit from Drains, Pipes, and the like, of which the following is aspecification.

This invention relates to scraper arrangements for removing deposit fromdrains, pipes and the like of the kind comprising a single blade sohinged to a 'drawbar' or equivalent that on moving the arrangement intoposition for use the blade is caused to assume an inoperative positionand on withdrawing thearrangement the blade is caused to assume itsoperative position.

Arrangements of the kind specified form the subject of application forLetters Patent granted to me, Serial No. 98,385, filed 18th May, 1916,the specification whereof describes examples wherein lines provided formoving the 'drawbar and blade or scraper alternately in oppositedirections actuate position controlling means adapted to cause thescraper to fall down against the drawbar or take up an operativeposition according to the direction in which the lines are moved.

The present invention has for object to provide simple and eificaciousmeans where- 'by for instance the-apparatus is rendered convenientlyapplicable to ordinary drain rods and for pipes, drains and the like ofrelatively small cross-sectional area.

For this purpose a device according to the invention comprises a drawbarprovided with a forwardly extending supplementary portion on which theblade is pivotally mounted and which is capable by the act of moving thedevice inwardly or outwardly of a pipe of sliding longtitudinallyrelatively to the rearwardly extending main portion of the drawbar, thetwo portions coacting with connecting means that serve to move the bladeinto its inoperative or operative positions respectively.

The invention can be carried into effect in various ways, one examplewhereof, applicable for attachment to a drain rod, is illustrated in theaccompanying drawings wherein Figure 1 is a plan and Fig. 2 a sideelevation of a device according to the invention showing the blade inits closed or inoperative position and Fig. 3 a View corresponding toFig. 2 but showing the blade in its open or operative position.

According to this example the rearward portion a of the drawbarconstitutes a sleeve adapted to so receive the inner end of the forwardportion 0 carrying the blade d that the ortion '0 can be freelyreciprocated therein, the interconnection between the portions 44 and 0being effected by a link 6 pivoted at or near the circumference of theblade (Z to a lug thereon and at its other end to a lug g on the sleeveconstituting the rearward portion a of the drawbar. The arrangement issuch that pressure from the rear, as through the drain rod Z), wheninserting the device into a pipe, will cause the portion a to slideforwardly along the companion portion 0, thus reducing the 'longitudinal distance between their forward ends thereby causing the blade (Zto assume its inoperative position (Figs. 1 and 2). Conversely, uponpulling the drain rod 7) in the opposite direction the said longitudinaldistance between the portions a and 0 will be increased and the blade 65thereby brought into operative position, (Fig. 8). i I

To limit the relative movement between the portions a and 0 according torequire ment, one thereof, may be formed with a longitudinal slot orslots having a length corresponding with the required degree" of traveland the other portion with a pin or pins projecting into the slot orslots. In the example the portion a is formed with a longitudinal slot hand the other portion a with a pin conveniently a set screw 7, thatprojects into the slot.

For attaching the device to the drain rod in such manner that rotationof either about its axis shall not involve rotation of the other, aswivel or like joint is interposed between the portion a of the drawbarand the drain rod. Such jointing means may comprise, as in the example,a pair of blocks 70 and Z or equivalent, slightly spaced apart one infront of the other, one end of the block Z1; having the portion asecured therein and the farther end of the block Z being secured as by athreaded part m to the cor-. respondingly threaded drain rod, the twobeing connected through alined longitudinal perforations n and 0 by abolt 29 about the shank of which the block is and the drawbar can freelyrotate relatively to the block Z and the drain rod.

What I claim is 1. Means of the kind described comprising a draw-barcomposed of a'forwardly extending longitudinally movable supplementarymember and a rearwardly extending main member, a blade pivotedintermediate of its width on said supplementary member, adapted whenmoved int-o its operative po sition to substantially fit the bore of thedrain pipe or the like to be cleaned, means connecting the blade and therearwardly extending main member of said drawbar, said means coacting,upon moving the device inwardly or outwardly of a pipe, with the bladeand the rearwardly extending main member to effect a longitudinalmovement of the supplementary member relatively to the main member andsimultaneously to rotate the blade into aninoperative or operativeposition according to the direction of movement.

2. Means of the kind described compris-,

ing a drawbar, composed of a forwardly extending supplementary memberoifset intermediately of its ends and a rearwardly extending mainmember, a blade, pivoted on said supplementary member at its ofisetportion, a lug on the blade, a corresponding lug on the main member anda link connecting said lugs, said link coacting with the main andsupplementary members to efiect a longitudinal movement of thesupplementary member to move the blade into an inoperative or operativeposition according to the direction of. movement.

8. Means of the kind described comprising a drawbar composed of aforwardly extending supplementary member and a rearwardly extending mainmember, a blade pivoted on said supplementary member, means connectingsaid blade and the main member, said means coacting with the blade andthe rearwardly extending main member to move the blade into aninoperative or operative position as required, a drain rod fitting andconnecting means between the rearwardly extending main member and saiddrain rod fitting adapted to prevent rotation of either causing rotationof the other. I

4:. Means of the kind described comprising a drawbar composed of aforwardly extending supplementary member and a rearwardly extending mainmember, a blade,

pivoted on said supplementary member, means connecting said blade andthe main member, said means coasting with the blade and the rearwardlyextending main memher to move the blade into an inoperative or operativeposition as required, a drain rod fitting and a swivel device connectingthe rearwardly extending member and the drain rod fitting.

5. Means of the kind described comprising a draw var composed of aforwardly extending supplementary member and a rear wardly extendingmain member, a blade pivoted on said supplementary member, meansconnecting said blade and the main member, said means coacting with theblade and the rearwardly extending main member to move the blade into aninoperative or operative position as required, a bolt carried on therearwardly extending main member, the head of said bolt being rotatablyseated therein and a drain rod,

fitting secured to the shank of said bolt and adapted for attachment toa drain rod.
